Russell finally had his fill of the man's mindless yelling and left the stage in search for the culprit!

After turning the house lights up and enlisting the audience's help, Russell ascended upon the mouthy instigator, and REAMED him out for a good three or four minutes.

One deliciously snarky highlight:

"I was hoping that your personality was a result of physical beauty, and then I saw you. I thought, This guy's confident because he's incredibly handsome. But look at you. You look like something that's fallen off the side of a church [likening the man to a gargoyle]. And what is it that you have rattling around in your mind? Some bizarre combination of alcohol and idiocy. Some cocktail of nothing. And yet you have the confidence to continue shouting."

Russell did end his rant by saying he loved the heckler, but obviously the audience member had hit a nerve…

Watch the curse-riddled ridicule (above). The video quality is a tad fuzzy but the audio is crystal clear.

I thought he was stronger, but now it's obvious to me that he still loves Katy. His reaction proves that he has so much pain and anger in his soul. She must have done something completely vile to him…he doesn't even want to hear her name. That's a typical reaction of a heartbroken person. Stay strong Russell. I love u.

I've met Russell twice and he's the sweetest, most gentle and down to earth celebrity I've ever met. This reaction is a strong proof that Katy is still in his heart. He hasn't moved on and this is sad, because she's obviously over him.

uhhh that was the WORST retaliation ive ever heard. so not funny witty or clever. it didnt even make sense. russell brand is so not funny and he shouldnt be commenting on ANYONES looks when his face looks like baraka from mortal kombat

What a genius! Russell was able to turn this akward moment into a funny situation! Even though his pain is obvious to the blind person. He is still suffering. I can't blame him. Katy showed NO RESPECT to him after the divorce. All this trashing to the media and that flaunting of her new bf at Coachella. You deserve better Russell. You deserve a woman who would respect u. Move on and forget her.

I was in the audience, sitting 2 rows behind the person who yelled out "Katy Perry". It was, in fact, one of his countrymen, sitting in the front row of the middle section and quaffing alcohol, (whom Russell had greeted warmly when he started his show by roaming the audience), who had shouted this, NOT the guy who eventually suffered the tongue-lashing from Russell. I couldn't even understand what the second guy shouted. I was embarrassed for Russell, who I'm sure would be unhappy to know this.

Haters should give Russell a break. How would you react if you were doing a show and some annoying idiot was shouting your ex wife's name? That guy was rude and did it on purpose to upset Russell. Plus, I'm sure Russell regretted his behavior because at the end he told him that he loved him. He lost his temper because he is still hurting. Leave him alone and don't judge.

I love Russell Brand. Hecklers are cowards. That's why that guy was trying to hide, but got ratted out by the audience. A true comedian would've and can do exactly what Russell did. Good for you Russell for shutting down a bully while you were working. I know that you will find love again. You're smart, sweet, and talented (not "Arthur" though. . .lol).

LOL @ the people mad at Rusell. I bet you guys are just as rude, immature, and negative like the loser who kept shouted his ex wife's name. When you're trying to perform, and some attention seeking loser keeps shouting your ex's name - you're going to get annoyed as well.

There always comes a moment where we explode for the most insignificant reason, but then we regret it, just because we have so much unexpressed pain within us. I think this is the case for Russell. He has remained silent for 4 months now, even though I'm sure he has a lot to say, and he exploded just because an attention seeker was yelling his ex wife's name. That guy showed no respect to Russell and wonder why did he go to his show if he didn't like him. One advice to Russell. Move on. Katy doesn't deserve your love. She's in love with her fame.

I dont think this shows weakness. This is a live show. He needs to focus on his jokes and the audience needs to hear what he's saying. They paid money to see and hear him, not some clown in the audience. If I was there and he didn't do what he did, I'd be pissed. And I don't think it would have mattered what the person was saying.

We were there…..front row!!!! That guy was obnoxious and deserved it. The first time Russell shut him down from the stage and any normal person would have be embarrassed and shut up…not this guy! He deserved everything Russell said! Despite what many think of Russell in the US, he really is an awesome guy! He hugged my daughter and visited with a lot of the audience.

Re: alyssa – Obviously you are a 10 year old Katy Perry fan who knows NOTHING. Cheated? Just because her stupid BFF said so? YEAH RIGHT. Dated 4 women? According to whom? This is tabloid trash. Every woman who sneezes next to him, they call it a date. AND if I remember well, Katy was the one flaunting and kissing in public her new bf at Coachella. Russell never showed any affection with a new woman in public. DEAL WITH IT. Katy showed her true colors. NOT Russell.
